thanks for digging, that's intriguing. The XLFD allowed in ancient times
for transformations, didn't know that. Not that it is relevant for now,
since we all render our texts in Tk using libxft. But until 2.3.5, that 
library, too, had still problems scaling/rotating/translating
bitmap fonts (especially the color emojis).

And yes, the challenge now is to make the rectangle (ahem, rotated, a
polygon) for a somewhat rotated text out of its bbox (if you'd like to
have a text background).

And please, enhance the wiki in this regard.
